I'm observing the same issue on 10.04 mythbuntu installation, with the same traceback.
The file doesn't exist ~/.config/ubuntuone/syncdaemon.conf I've only just come to try using Ubuntu One with Rhythmbox on the affected PC. I've never been able to run the preferences application. Rhythmbox synced to Ubuntu One storage one time and successfully pulled in the music files. I bought more tracks but have not been able to sync them to the mythbuntu PC. $ dpkg-query -l '*ubuntuone*' Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description +++-=====================-=====================-========================================================== ii libubuntuone-1.0-1 0.3.1-0ubuntu1 Ubuntu One widget library un nautilus-ubuntuone <none> (no description available) ii python-ubuntuone 0.3.1-0ubuntu1 Ubuntu One widget library ii python-ubuntuone-clie 1.2.2-0ubuntu2 Ubuntu One client Python libraries ii python-ubuntuone-stor 1.2.0-0ubuntu1 Python library for Ubuntu One file storage and sharing ser un python2.6-ubuntuone <none> (no description available) un python2.6-ubuntuone-c <none> (no description available) un python2.6-ubuntuone-s <none> (no description available) ii rhythmbox-ubuntuone-m 0.0.9-0ubuntu1 Ubuntu One Music Store Rhythmbox plugin ii ubuntuone-client 1.2.2-0ubuntu2 Ubuntu One client ii ubuntuone-client-gnom 1.2.2-0ubuntu2 Ubuntu One client GNOME integration un ubuntuone-oauth-login <none> (no description available) un ubuntuone-storage-pro <none> (no description available) un ubuntuone-storagefs <none> (no description available) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/666608 Title: Ubuntuone-client software wont start even after fresh install of the software packages. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
